Imitative polyphony often printed religious in nature.
Answer:
16 km/h
Explanation:
The relay stick would have the same velocity relative to Ingrid as the velocity she threw it because she threw it while running 9 km/h and the question asks for how fast it is moving RELATIVE to Ingrid, who also started off moving at 9 km/h.
Sorry if explanation is bad, this one was a bit of head scratcher for me to wrap my head around ig.
The price elasticities of demand of sugar-free gummy bears and of ordinary gummy bears is -0.8 and -2.3 respectively.
<h3>How to calculate price elasticity</h3>
Change in price of gummy bears = $2. 60 to $3
Elasticity of demand of sugar-free gummy bears =
[(273-379 / (273+379)/2] ÷ [(3.00-2.60)/(3.00+2.60) / 2]
= [-18/166] / [0.4/2.8]
= -0.10843373493975 / 0.14285714285714
= - 0.75903614457826
Approximately, -0.8
Elasticity of demand of regular gummy bears:
Sugar free = [(273-379) / (273+379)/2] ÷ (3.00 +2.60) / 2]
= [-106/326] / [0.4/2.8]
= -0.32515337423312 / 0.14285714285714
= -2.2760736196318
Approximately, -2.3
